JavaScript: Parse this string

Here is a long string (actually a JSON key value):

"\u003cspan title=\"5 gold badges\"\u003e\u003cspan class=\"badge1\"\u003e●\u003c/span\u003e\u003cspan class=\"badgecount\"\u003e5\u003c/span\u003e\u003c/span\u003e\u003cspan title=\"8 silver badges\"\u003e\u003cspan class=\"badge2\"\u003e●\u003c/span\u003e\u003cspan class=\"badgecount\"\u003e8\u003c/span\u003e\u003c/span\u003e\u003cspan title=\"57 bronze badges\"\u003e\u003cspan class=\"badge3\"\u003e●\u003c/span\u003e\u003cspan class=\"badgecount\"\u003e57\u003c/span\u003e\u003c/span\u003e"

I need a way to parse it to get the number of gold, silver and bronze badges, using simple JScript in Dashcode.

function getBadgeCounts(s) {
  var badgeCountRE = /title="(\d+)/g, match = null, counts = [];
  while ((match = badgeCountRE.exec(s)) !== null) {
    counts.push(match[1]);
  }
  return {gold: counts[0], silver: counts[1], bronze: counts[2]};
}

Without hardcoded medal names:

function getBadgeCounts(s) {
  var badgeCountRE = /title="(\d+) (\w+)/g, match = null, counts = {};
  while ((match = badgeCountRE.exec(s)) !== null) {
    counts[match[2]] = match[1];
  }
  return counts;
}
